Abstract: A die cushion force control method and a die cushion apparatus generates a die cushion force on a cushion pad based on a die cushion force command value set in advance. A die cushion force command value equal to or larger than a target die cushion force command value is outputted initially in order to suppress an initial die cushion force overshoot generated when the target die cushion force command value configured to be stepwise is used as the die cushion force command value, then a die cushion force command value decreased continuously (gradually) so as to be smaller than the target die cushion force command value is outputted, and subsequently a die cushion force command value increasing gradually so as to be equal to the target die cushion force command value is outputted.

Abstract: This aims to provide a press process for drawing a plate material into a predetermined shape. This press process performs a first unwrinkling treatment and a second unwrinkling treatment sequentially for unwrinkling the material. Between these first and second unwrinkling treatments, an introduction for deforming the material is made so that the portion of the material on the side to be subjected to the second unwrinkling treatment may be positioned on the side of a drawing direction with respect to the portion subjected to the first unwrinkling treatment. This first unwrinkling treatment is made on such a portion to be unwrinkled in the material as is located on the side of a larger drawing depth for the predetermined shape. On the other hand, the second unwrinkling treatment is made on such a portion to be unwrinkled as is located on the side of a smaller drawing depth.

Abstract: In the die cushion device, a shock absorber device relieves shock between a cushion pad and a support section. The shock absorber device includes a damping section and an elastic section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section. The elastic section generates reaction force in accordance with the relative displacement of the cushion pad with respect to the support section. The controller section controls a servomotor so that a speed difference between the speed of the slide member and the speed of the support section is set to be a predetermined target speed difference value that changes over time.

Abstract: A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.

Abstract: A control device, for a servo die cushion, capable of improving a response after overshoot generated by collision of a slide and a die cushion. The control device has a local maximum point judging part which judges a local maximum point based on the detected speed of the servomotor; a speed correction value calculating part which calculates a speed correction value for the servomotor based on the judgment result and the detected speed of the slide; a second force commanding part which generates a second force command value, the second force command value decreasing from an initial value to a first force command value, the initial value being equal to the force detected value when reaching generally the local maximum point. The force command value is switched from the first force command value to the second force command value, when the force detected value reaches the local maximum point.
